Since 2018
For over 8 years, we've helped clients navigate Polish law, combining our solid legal knowledge with practical immigration experience.
Why foreigners underestimate Polish bookkeeping
Registering a business feels like the hard part. Then invoices start, contractors ask for VAT details, and calendars fill with ZUS and tax deadlines. The real risk is rarely “advanced math”. It is language, timing, and mismatched paperwork that surfaces months later as a fine, a bank rejection, or questions during a temporary residence card (TRC) case.
ONE PLUS has worked with foreigners and businesses in Poland since 2018. More than 12 years of hands-on practice in immigration and administrative matters help us treat accounting as part of your wider setup: activity, taxes, social contributions, and the story your numbers tell. Based in Wrocław, we support clients across Poland.
This page is general guidance. Final decisions on taxes and contributions belong to the tax office and ZUS.
What the service covers
Day-to-day books
We collect invoices, contracts, bank statements and costs, check consistency, and keep records under the tax model you use. For sole traders (JDG) that usually means revenue records or a revenue-and-expense ledger. For Sp. z o.o. companies it means full accounting and year-end reporting.
Tax returns
Depending on your structure we prepare PIT, VAT, VAT UE filings where needed, and CIT for companies. Annual returns and corrections are handled when the facts require them. Official references: podatki.gov.pl. If you also receive employment income, PIT-11 / PIT-37 support may be relevant.
ZUS and payroll
Registrations, contribution calculations, employment documents, hires and terminations. This is where many foreigners stumble: wrong insurance codes, missed deadlines, or confusion between employment contracts and B2B invoices.
External packs
Statements for banks, leasing, equipment rental, income confirmation, and materials that support a business plan for TRC. Offices look for coherence. CEIDG/KRS data, tax filings and contracts should describe the same business.
Who it fits
Freelancers and B2B specialists
Multiple clients, mixed currencies, occasional cross-border VAT questions. Monthly discipline matters more than sophisticated “optimisation”.
Trade and e-commerce
Purchases, logistics, returns and supplier docs. Without clean source documents, month-end becomes guesswork.
Companies with foreign shareholders
Higher formal burden, CIT, board payments, dividend questions, and often a parallel residence strategy for founders.
Founders preparing a residence case
Accounting creates a traceable history. Starting early is cheaper than rebuilding six months of chaos before an appointment.
JDG vs company: different accounting pressure
A JDG is lighter at the start, but your tax form (scale, flat rate, or lump-sum ryczałt) changes how income looks. An Sp. z o.o. needs fuller books and stronger document hygiene. There is no universal “cheapest” path. Choice depends on risk, partners and growth plans.
Without PESEL, many e-government and banking flows are harder. Business address and registration of residence (zameldowanie) also affect official mail. We check that registry, bank and accounting data match.
How cooperation works
- Short briefing: entity type, turnover, VAT, staff.
- Contract with a clear scope and fee.
- Document channel setup.
- Monthly calculations and filings.
- Payment reminders with plain-language explanations.
- Optional packs for banks or immigration procedures.
Useful public portals: biznes.gov.pl. We translate obligations into your checklist, not into vague slogans.
Mistakes we see every month
Mixing personal and business spending
Makes profit hard to prove and weakens banking or TRC evidence.
Late VAT or ZUS registration
Consequences arrive late and usually cost more than an early consult.
Conflicting addresses and names across systems
Small mismatches trigger letters and delivery problems.
Invoices without contracts
Harder to defend costs or show stable revenue when asked.
Practical notes for 2026
Digital filing is convenient, but less forgiving. Missed returns, incomplete attachments or silent gaps in source documents create follow-up requests. On practice, foreigners lose time more often to process discipline than to tax theory.
If you are still registering a business, a sensible order is: confirm your right to operate, arrange PESEL if needed, register the activity, then connect accounting from month one. Catch-up bookkeeping is possible, but slower.
ONE PLUS works under contract, from a Wrocław office, with transparent scope. We do not replace public authorities and we do not promise “zero audits”. We reduce avoidable errors and keep deadlines under control.
